Re: sensors, looks like it's new equipment (no surprise). From a translation of http://horizonhobby.de/index.php?mai...=&prod_id=6463
The facilities of other models, the telemetry modules and boards / sensors are also available separately. Each spectrum receiver with a data port is compatible with the telemetry module.
SPM9548 Telemetry Module
SPM9560 Air Speed Sensor Telemetry Board
SPMA9569 Air speed sensor
SPM9561 Aircraft telemetry battery power board
SPMA9570 battery voltage Sensor
SPM9562 Aircraft Telemetry Temperature Sensor Board
SPMA9571 Aircraft Temperature Sensor
Connecting in series of connected boards are available in lengths.
6 "= 15.24 cm SPM9563
9 "= 22.86 cm SPM9564
12 "= 30.48 cm SPM9565
Here's a German site
that suggests some pricing for these components.
